Now your Scared for life ,next pair it will be all good ,I know 30 years + ,,new pair takes a week or so to break in ..WHEN IT'S NOT BROKE ,,,DONT FIX IT
secret to a great shape ,,,is knowing when to stop

The Hemp ones are much easier to break in and are alot more comfortable, but they dont last near as long. I go through about a pair a year, but i do wear flip flops everyday of the year.... Most comfortable flop ive ever had.
